- CASE::001 — Native Wi-Fi Stack · ZephyrRTOS
[ CHALLENGE ] ZephyrRTOS had offloaded Wi-Fi only — basic connection management delegated entirely to vendor firmware. No native supplicant meant every feature addition, bug fix, or security update depended on the silicon vendor's roadmap and release cycle, with no ability to extend or debug independently.
[ OUTCOME ] Evaluated integration paths — iwd, proprietary options, and hostap — and selected hostap as the right foundation: proven, upstream-maintained, and protocol-complete. Ported hostap from Linux to ZephyrRTOS, designing clean integration hooks into Zephyr's networking stack and driver model. The native stack gives device manufacturers full ownership of the supplicant layer — no vendor dependency for features, fixes, or debug. Maintained upstream as the official Zephyr Project Wi-Fi Maintainer.
- CASE::002 — HW-SW Co-Design Validation · 802.11ax Pre-Silicon
[ CHALLENGE ] Silicon vendor needed maximum software validation of their 802.11ax IP before tape-out. Bugs caught post-silicon mean re-spin costs and schedule slip; the goal was to exercise as much of the Wi-Fi stack as possible before real hardware existed.
[ OUTCOME ] Developed a HW-SW co-design validation strategy using the vendor's existing simulators, emulators, and FPGA environments — adapted specifically for 802.11ax protocol testing. Innovated a peer simulation approach enabling full protocol-level testing with and without RF hardware. Critical Wi-Fi IP integration bugs and performance issues were identified and resolved pre-tape-out; new 802.11ax features were validated before silicon was available, compressing the post-tape-out bringup timeline significantly.
- CASE::003 — MbedTLS 4.x Migration · Wi-Fi Security Stack (ZephyrRTOS / NCS)
[ CHALLENGE ] Wi-Fi security in ZephyrRTOS and silicon vendor stacks ran on legacy MbedTLS APIs. MbedTLS 4.x + TF-PSA-Crypto was required for PSA Certified compliance and EU Cyber Resilience Act readiness — but 4.x removed or privatised primitives Wi-Fi security protocols depend on: DHM dropped entirely, ECP curves (secp192r1, 224r1/k1) gone, legacy crypto headers made private. WPA3-PSA was not yet a MbedTLS project priority, requiring community-level pressure to land it.
[ OUTCOME ] Ported hostap within ZephyrRTOS to work with MbedTLS 4.x + TF-PSA-Crypto LTS — adapting to a set of breaking changes that had no upstream hostap support. Manually ported DHM into hostap; disabled dropped ECP curves from TLS handshakes; resolved private header access for upstream integration. Coordinated testing across Nordic Semiconductor, NXP, and the MbedTLS team — running mac80211_hwsim simulation testing while vendors covered hardware validation. All Wi-Fi security modes (Personal, Enterprise, WPS, DPP) ported to PSA APIs with fallbacks for gaps in the spec. Integration into Nordic Connect SDK (NCS) ongoing.

[ 0x05: TEAM_STRUCTURE ]
user@lab:~$ ls -l /organization/
- Founder & CTO (Chaitanya Tata) — Sole point of accountability on every engagement. Owns scoping, architecture, delivery, and sign-off. You always have a named principal with skin in the game, not a project manager fronting a team you'll never meet.
- Vetted Senior Associates — Domain specialists pulled in per engagement as the scope demands. No junior bench, no staffing-agency placements. Associates are selected for the specific technical depth the problem requires.
- Engagement Model — Structured to fit the work: fixed-scope, time-boxed, or ongoing T&M. Every deliverable is reviewed and signed off at principal level before release. Scope and billing structure are agreed upfront — no surprises.
[ INFO ] All work reviewed and signed off at principal level. No black-box subcontracting.
[ 0x02: OPERATIONAL_VELOCITY ]
user@lab:~$ ./dotstar --efficiency-report
Dotstar delivers senior architectural precision at the pace of a multi-engineer team. Engagements are scoped tightly, milestones are defined upfront, and every deliverable is reviewed and signed off at principal level before it reaches you.
- Faster delivery Modern engineering tooling — including AI-assisted code generation and automated test coverage — accelerates timelines without trading off quality or correctness. Engagements that typically take months move in weeks.
- Cost efficiency You get the output of a multi-engineer team at boutique firm rates, without the headcount, onboarding overhead, or management burden of building one.
- No unreviewed output Every line of code — tool-generated or handwritten — goes through a senior principal review before release. You are never handed output that hasn't been through a senior technical review.
[ INFO ] Strategic engineering partner: principal-led, outcome-accountable, NDA-standard.
[ 0x03: GOVERNANCE_&_COMPLIANCE ]
user@lab:~$ ./check_compliance --results
All work product is assigned to the client upon payment. Any open-source components are disclosed upfront with licence classification. No proprietary Dotstar code is silently embedded in deliverables — what you receive is yours, clean.
Dotstar's principal holds active maintainer and core-contributor status across the Wi‑Fi and IoT open-source stack (see Founder credentials). Contributions land upstream, so your codebase inherits long-term community maintenance rather than an orphaned fork.
Dotstar supports certification workflows for WFA (Wi‑Fi Alliance), CSA (Matter/Thread), FCC/ETSI/CE, and PSA Certified. Deliverables include test automation frameworks and interoperability test suites compatible with DevOps pipelines.
NDA-first engagements as standard. No cross-client disclosure. Associates brought in for a specific engagement are not briefed on unrelated client work. Compartmentalisation is structural, not policy-dependent.
