More on me.

3+ years of professional engineering · 2.5y at EY + 6mo co-op

I'm Archit, a software engineer and CS Master's student at Northeastern, based in Boston. Before grad school, I spent 2.5 years at Ernst & Young in Delhi building full-stack applications for Fortune 500 clients, including contributing to EY.AI, a generative AI platform that scaled to 400,000+ users at 99.9% uptime.

I work across the stack: React, Next.js, and TypeScript on the frontend; Go, Node, and Python on the backend, with deeper interests in AI/ML systems and data infrastructure. I'm currently interning at Abacus Health Solutions, where I've been shipping production features using TypeScript, Go, REST APIs, Sentry, and AWS. On the side, I TA'd CS1800 (Discrete Structures) at Khoury, which turned out to be one of the most useful things I've done for my own engineering thinking.

Code I'm proud of.

The cache-aside redirect path from url-shortener. Reads warm the Redis cache on the cold path, fail open if Redis hiccups, and capture clicks asynchronously so the redirect itself stays fast. Observability via Sentry spans on both legs.

backend/internal/services/url_service.go 
// Resolve looks up a short code and returns the long URL.
// Cache-aside on the redirect hot path: Redis hit ~1ms, cold path ~5ms via pgx.
func (s *URLService) Resolve(ctx context.Context, shortCode string, clickCtx *ClickContext) (string, error) {
    span := sentry.StartSpan(ctx, "service.resolve")
    defer span.Finish()

    var longURL string
    var urlID int64

    // Fast path — Redis. Click metadata still needs the row id so we
    // do a lightweight lookup only when a recorder is attached.
    cached, err := s.cache.Get(ctx, shortCode)
    if err == nil {
        longURL = cached
        span.SetTag("cache.hit", "true")
        if clickCtx != nil && s.recorder != nil {
            if u, lookupErr := s.repo.GetByShortCode(ctx, shortCode); lookupErr == nil {
                urlID = u.ID
            }
        }
    } else {
        // Cold path — Postgres + warm the cache on the way back.
        // Graceful degradation: a Redis hiccup still serves the redirect.
        span.SetTag("cache.hit", "false")
        if !errors.Is(err, cache.ErrCacheMiss) {
            s.log.Warn("cache get failed, falling back to db",
                "short_code", shortCode, "error", err)
        }
        u, err := s.repo.GetByShortCode(ctx, shortCode)
        if err != nil {
            return "", err
        }
        longURL, urlID = u.LongURL, u.ID
        _ = s.cache.Set(ctx, shortCode, u.LongURL) // best-effort warm
    }

    // Fire-and-forget click capture so the redirect isn't blocked.
    if clickCtx != nil && s.recorder != nil {
        s.recorder.Record(repository.Click{
            URLID:     urlID,
            IPHash:    hashIP(clickCtx.IP),
            UserAgent: clickCtx.UserAgent,
            Referrer:  clickCtx.Referrer,
            ClickedAt: time.Now(),
        })
    }

    return longURL, nil
}
